(CBS) All it took was one customer and a stinky bottle to push Pfizer to voluntarily recall 19,000 bottles of Lipitor, its blockbuster cholesterol drug.
This is the fourth recall of the product this year because of "uncharacteristic odors."
A company press release says they believe the smell comes from a wood preservative called tribromonophenol which is often applied to shipping pallets. Pfizer says they banned the practice and the recalled products were bottled by a third party company.
The company said "a medical assessment found that the risk of health consequences to patients appears to be minimal" and it doesn't expect a shortage.
